DYEING AND OXIDIZING- 'MACHINE. 7

Application filed. August 4,1924. Serial No. 730,010.

This invention relates to raw stock cotton dyeing and oxidizing apparatus of the type known as the continuous type and shown in my pending application Ser. No. 7 08,7 89.

The object of the invention is to provide an apparatus of this character similar to that shown in the application above referred to omitting the oxidizing screens in the application referred to and substituting a hopper whereby the same results are obtained with less machinery and Which simplifies and cheapens the cost of the machinery.

Another object of the invention'is to provide an apparatus of this character equipped with means for supplying dye to the vat as needed thus insuring keeping up the strength of the dye as it is used.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

The accompanyingdrawing shows a side elevation partly in section of an apparatus constructed in accordance with this invention.

In the embodimentillustrated a plurality of dye vats or boxes 1 are employed arranged preferably in longitudinal alinement in the same plane, in connection with which are used feed hoppers 2, one being employed for v each vat as is shown in the drawing. These vats and hoppers are exactly alike in 06nstruction and hence one only Will' be described in detail,

The hopper 2 is provided at its upper end with an inlet '8 for the cotton to be treated and the cotton entering at this inlet will drop onto a plain apron 4 arranged in the bottom of the hopper and extending horizontally. This apron 4 feeds the cotton to a spike apron 5 arranged vertically or substantially so in the hopper 2 near the front end thereof. This spiked apron picks up the cotton from the apron 4 and carries it to the upper end of the hopper where it is dotted by a dofiing roller 6 into and through into the dye vat 1.

a discharge pipe 7 which delivers the cotton The cotton after being subjected to the dyeing action in the vat l is carried by a spiked apron 8 and delivered by .a doffer 9 to the squeeze rolls 10. The cotton after passing through the squeeze roll 10 is delivered by a doffer 11 onto the apron 12 and from there passes into the fan hopper 13. From the hopper 13 the cotton passes to the fan 14 and through the fan outlet 15 into the next feed hopper 2, the delivery spout 15 being shown in the form of a goose-neck. This operation is repeated as many times as may be found necessary or desirable.

A dye supply tank 16 is mounted above each vat 1 and has a pipe 17 leading therefrom to the bottom of vat l and said pipe is then extended laterally as shown at 18 and perforated to deliver the dye to the bottom of the vat. A valve 19 is arranged, in the pipe 17 for regulating the feed of the dye from tank 16.

The cotton after leaving the last dye vat l is ready for oxidizing and drying which may be accomplished by any suitable apparatus, not shown.

The fan 14 acts as a conveyor and the draft like suction created by the fan operates as an oxidizer and a dryer. The oxidiz ing and drying operation is further carried out by the feed hoppers 2 since'the cotton discharged from the spout 15 is delivered into said hopper onto the apron 4 and from said apron is picked up by the spiked apron 5 and carried to the top of the hopper thus exposing the cotton to a drying and oxidizing action before it passes onto the next dye ing vat.

I claim 1. Ina cotton oxidizing and dyeing apparatus the combination of dye vats, a feed I hopper for each of said vats having upright and horizontally disposed aprons for conveying cotton through the hopper, a spout discharging from said hopper into one of said vats and into which the cotton is delivspout to deliver it to the next hopper.

'2. In an apparatus of the class described, a dye vat, aprons for conveying cotton through said vat, one of said aprons extending up out of the vat, squeeze rolls cooperating with said apron, a fan having a hopper arranged to receive the cotton from said squeeze rolls, a discharge spout leading from said fan and through Which the cotton is designed to be conveyed, and a feed hopper into which the cotton from said spout is delivered.

In testimony that I claim the foregoing 10 as my own, I have hereto afiixed my signature.

JONES C. MQFALLS.
